Further, the movable frame 5 is provided with a folding plate 8 and a girder top plate 9 as a set on both sides of the pusher 6, and the two constitute a folding member 10.

The folding plate 8 is adjusted and fixed at a position in contact with each end face in the length direction of the product, and the lower edge 8' of each plate 8 reaches directly above the support stands 1, 1, that is, on the support stands 1, 1. It should be positioned so that it approximately coincides with the bottom surface of the product A.

The folding plate 8 is formed into a protruding shape by cutting the front part of the flat plate part 8'' constituting it into an L shape, and has a length that protrudes forward from the bushing 6 by an appropriate length in the transport direction.

The girder upper plate 9 is a vertically elongated rectangular flat plate mounted on the folding plate 8, and its rear edge is swingably connected to the flat plate portion 8'' by a hinge 11.

The girder upper plate 9 is provided with a support shaft 30 that projects upward, and a roller 31 is rotatably attached to the upper end of the shaft 30 so that the roller 31 slides into contact with the inner surface of the guide frame 32 as the movable frame 5 moves. A spring 33 is hooked to the support shaft 30 to allow the roller 31 to roll and to urge the roller 31 to constantly contact the guide plate 32.

The guide plate 32 is connected to the roller 31. It has a guide surface 32' that holds the girder upper plate 9 in an outwardly open state via a support shaft 30, and an operating surface 32'' that protrudes inward from the guide surface 32' at the front thereof. When the roller 31 rolls on the operating surface 32'', the girder plate 9 swings to the product end surface position.

A folding plate 12 is installed at the front of the packaging section A on a line facing the folding member 10.

The folding plate 12 is made of a wall member that stands up on its lower edge 12' and has its rear part protruding behind the lower edge 12', and its upper edge is formed at a height that projects an appropriate length above the product 4. do.

The upper part of the folding plate 12 is slightly inclined outward, and the rear part is inclined outwardly so that the opening of the wrapping paper can be folded in and folded up easily.

Further, a return plate 13, an ear folding plate 14, a guide plate 15, and a folding rod 16 are installed in front of the folding plate on the transfer path a, and an elevator is installed below between the folding rods 16 and 16 at the end of the transfer path a. 17 will be installed.

The wrapping paper opening is arranged between the elevator 2 and the support stands 1, 1 so that the wrapping paper is fed out according to the size of the product A, and at the rear of the elevator 2, one piece of the product A is placed onto the elevator 2. A transfer path 18 is provided in succession.

To explain the wrapping operation, the product I transferred from the transfer path 18 to the elevator 2 in the body wrapper A moves upward between the supports 1 and 1 while pushing up the wrapping paper opening as the elevator 2 rises. The edges of the iron platforms 1, 1 are pushed out and supported by riding on the platforms 1, 1, and the elevator 2 then descends.

Thereafter, the bottom folding plate 3 is inserted along the bottom surface of the product, so that the rear part of the wrapping paper opening is folded along the bottom surface of the product.

Next, the movable frame 5 moves toward the packaging section A, and the folding plate 8 folds the rear side edge 20-1 of the opening end 20 of the wrapping paper opening protruding from both ends of the product A along the end surface of the product A, and the roller 31 rides on the operating surface 32'' of the guide plate 32, the girder plate 9 swings toward the product side, folding the upper part of the side edge 20-1 along the end surface and folding the upper edge 20-3 continuous thereto.
Fold the rear part upward vertically (Figure 3).

After the above-mentioned folding operation, the pusher 6 hits the product A with a slight delay and pushes the product onto the transfer path a, so that the front part of the wrapping paper opening uses the front support 1 as a folding piece and is folded into the bottom of the product A. Then, as the wrapping paper opening is wrapped around the body, the folding plate 12 hits the front side edge 20-2 of the opening end 20 and folds the side edge 20-2 along the end surface of the product, and then folds the upper edge continuously thereto. Fold up 20-3 upwards (Figures 4 and 5).

Side edges 20-, .
By folding up the upper edge 20-3 following the folding 20-2, the upper edge 20-3 is formed into a predetermined lug shape with both side ends folded into a triangular shape (FIG. 6).

The subsequent transfer of the product A is carried out by the pusher 7 during the next stroke after the movable frame 5 has taken one stroke, and the folded-up upper edge 20-3 of the product A comes into contact with the return plate 13 and moves along the iron plate 13. It is folded back horizontally and the lower edge 20-4 forms the edge folding plate 1.
4 and is folded into the end face of the product by the iron plate 14 (Fig. 7), and then the upper edge 20-3 is moved onto the elevator 17 at the end of the transfer path a while maintaining a horizontal state along the guide plate 15, and then The elevator 17 rises and the product A moves to the folding rod 1.
6.16 and when passing between the rods 16, 16, the upper edge 20-3 is folded along the end surface of the product and overlapped with the previously folded lower edge 20-4 ( 8th
figure form).

Incidentally, reference numeral 19.19 in the figure is a heater, which is used to adhere the bottom folded portion of the wrapping paper opening that moves over the heater.

Next, FIGS. 9 and 10 show another embodiment of the present invention, in which a folding member 10' consisting of a folding plate 28 and a girder plate 29 is installed where the folding plate 12 of the above embodiment is located. This is what I did.

The folding plate 28 has a shape in which the front upper part of the folding plate 12 is cut out in the shape of ``'', and a girder upper plate 29 is attached to the cut out part with a hinge 27 so as to be able to swing freely toward the product side.

A support shaft 26 is integrally provided upward on the girder top plate 29, and a drive lever 25 is engaged with the support shaft 26, and the lever 25 swings the girder top plate 29 toward the product side via the support shaft 26. make it move.

The above-mentioned girder plates 9 and 29 are such that the product A is moved to some extent in the direction of the transfer path a by the pusher 6, and both the folding plates 8 and 28 are connected to the side edges 20-, . When 20-2 is folded into the end surface of the product, it simultaneously swings toward the end surface of the product A side, and the side edge 2
0-,. Continuing with the folding of 20-2, the upper edge 20-3 is folded up vertically.

For convenience of explanation, the same members as those in the advance sale embodiment are shown with the same reference numerals, and the explanation will be omitted.

Since the present invention is constructed as described above, the opening end of the wrapping paper of a product wrapped around a pair of left and right folding members consisting of a folding plate and a girder plate, or a folding member on one side and a folding plate on the other side. Both side edges of the product are folded along the end surface of the product, and the upper edge is folded upward substantially vertically.

Thus, the upper edge of the opening edge is formed into a predetermined lug shape by folding both side edges into a triangular shape by folding up and folding up the side edge, and the upper edge of the folding plate is raised steplessly. Therefore, the upper edge of the wrapping paper can be formed into a predetermined shape regardless of the height of the product.

Therefore, the conventional work of adjusting the height of the folding claws for folding the side edges according to the height of the product or replacing the folding claws is no longer necessary, and it is possible to provide a packaging device that improves work efficiency.

Also, since the upper plate is swung from the side toward the end surface of the product to fold up the upper edge, the folding plate allows the side edges 20-, . At the point where 20-2 is folded in, the upper edge 20-
A small crushed strong part R is formed at the end of 3 (the stiffness becomes especially strong when the paper thickness is large or the paper quality is hard) (Fig. 11), but this part R is By swinging the plate, the plate is smoothly pressed against the end face of the product and folded upward (Fig. 12), and a predetermined lug shape is reliably formed on the upper edge 20-3, thereby improving workability. Moreover, the folding operation is more reliable than a structure in which the girder plate is rotated upward along the end surface of the product.
